I have an old laptop I'd like to repurpose as a print/SSH server (among a few other light tasks). The laptop has a 2.0GHz Pentium M processor with 1GB of RAM (to be specific, its an old Dell Precision M60). The system is running Ubuntu Server 10.04. A combination of htop and my screen config show that the CPU is constantly running at its full speed, even when under little/no load -- this was not an issue under 9.04 and 9.10. I'd like to drop the speed of the processor down to save on power, heat, and noise.

I've poked around in the BIOS for the P-M60 a bunch, but never seen anything for setting the CPU speed only. Unfortunately, Intel processors are always multiplier-locked, so I'd have to downclock the entire system to do this.

Yes, downclocking the entire system would be the outcome.
